Title: Motion control device for vehicle
Inventor: MATSUNO KOJI
IPC: B60W30/09
Filed: 2000-03-03
Abstract: PROBLEM TO BE SOLVED: To surely avoid a vehicle from contacting a front obstacle by performing avoidance by turning when avoidance by deceleration is insufficient to avoid the vehicle from contacting the front obstacle. SOLUTION: In a control device 15, a deceleration judging part 15c, a deceleration arithmetic part 15d and a brake control part 15e perform automatic braking by a distance from the front obstacle, speed and a road gradient to avoid the vehicle from contacting the front obstacle. When contact avoidance from the front obstacle by deceleration is decided to be impossible in a braking distance deciding part 15f, a first yaw rate arithmetic part 15g and a second yaw rate arithmetic part 15h calculate a first yaw rate required to avoid the front obstacle by turning and a second yaw rate generated in the present vehicle, respectively. In a target yaw rate setting part 15i, the first yaw rate and the second yaw rate are compared and the yaw rate of a larger absolute value is set as a target yaw rate. An automatic brake control part 15j calculates target braking force based on at least the target yaw rate, selects a braking wheel and performs a vehicle behavior control.

Title: METHOD FOR MANUFACTURING SiC COATED GRAPHITE MEMBER WITH REDUCE PINHOLES

Filed: 2000-03-15
Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a long-life silicon carbide coated graphite member free from pinhole even in a high temperature gaseous hydrogen chloride atmosphere and excellent in oxidation resistance particularly at high temperatures. SOLUTION: Particular attention is paid to the positional relationship between graphite as a base material and an SiC-forming atmosphere in high temperature gas phase, and it is found that a spot where a silicon molecule is deposited in an unreacted state is brought about owing to the specific-gravity difference or concentration difference between silicon component in raw material decomposition gas and carbon source gas, which is presumed to be the cause of pinhole. Accordingly, in the method for manufacturing the SiC coated graphite member where SiC is deposited on the graphite base material by chemical vapor deposition(CVD), source gas of ordinary composition is uniformly supplied to the graphite base material, while source gas enriched in gaseous hydrocarbon as a carbon source is supplied from the vicinity of the graphite base material.

Title: Active matrix type liquid crystal display device
Inventor: MIYAJIMA KOJI
IPC: G09G3/36
Filed: 2000-03-28
Abstract: PROBLEM TO BE SOLVED: To provide a liquid crystal display device whose drop voltage is small even if parasitic capacitance is large; when a gate voltage is inputted in a rectangular pulse form, voltage variation, what is called a drop voltage, in a pixel electrode is caused by being pulled by the fall of the gate voltage due to the parasitic capacitance between the gate line and the pixel electrode.
